Scientists discover giant Rydberg atom molecules

June 24, 2009

A group of University of Oklahoma researchers led by Dr. James P. Shaffer, Homer L. Dodge Department of Physics and Astronomy, have discovered giant Rydberg molecules with a bond as large as a red blood cell. Determining how Rydberg molecules interact is important because Rydberg atoms are a key ingredient in atom based quantum computation schemes.

Giant Rydberg are formed when two Rydberg interact. A Rydberg atom is an atom that has at least one electron orbiting the nucleus at a very large distance. A giant molecule can form from two Rydberg atoms when they are in close proximity to one another because fluctuations of the electron orbiting the nucleus can create an electric field at the position of the other Rydberg atom and vice versa to attract the atoms to each other.

An additional electric field can change the orbit of the electrons and lead to a change in the forces acting between the Rydberg atoms. The ability to change the orbit of the electron with an electric field is what makes it possible to control the properties of the molecule, such as and vibrational frequencies. Applying an to tailor the properties of these types of molecules is a unique property.

The characteristics of the macroscopic molecules make them ideal candidates for probing quantum gases, properties of the electromagnetic field, and determining how Rydberg molecules interact. Shaffer says an understanding of these problems will bring us closer to a new generation of quantum mechanical devices that meld the best properties of isolated atomic systems with advances in microelectronic fabrication and materials science.

The research performed by Shaffer, K.R. Overstreet, A. Schwettmann, J. Tallant, and D. Booth is reported in the advanced online version (June) of and in the July issue of the scientific journal.

Alchemy at it's finest.

If one researches actual true alchemy (which is PURPOSELY hidden from mental infants!) They will find 'that which lies beyond this' within alchemy. Alchemy is not for the psychologically weak, as it's implications are multi-dimensional and transformative, which is what keeps it out of the hands of the mentally undeveloped. Specifically, it has always been a question of inner growth so one can understand and handle the implications of alchemy, it has -never- been the science.

It is the man attempting it, that has always been the issue. This, of course, is a path of the mentally developed and learned man, and the opposite, the mental infant - is a purely psychological issue and has little (actually..nothing) to do with the given individual's level of institutional training.

Alchemy (the transformation of "base" metals to gold) is possible through the use of a particle accelerator. However, it is energetically and economically unfavorable to produce gold this way. Additionally, as far as I know only very very small amounts of gold can be produced at one time.

On a different note, it's really cool to think that diatomic molecule could be made to have a bonds big enough to be seen with a microscope (if they interacted strongly with visible light, which I doubt they do.)

Purposely hidden from the religious to avoid being burned at the stake is not quite the same thing as you are claiming.

I see, those that disagree with your nonsense are automatically defined as weak. Yes that is such a strong argument. Every bit as reasonable as saying people will go to hell for not believing in hell.

Newton and Einstein had more than gravity in common. They both wasted enormous amounts of time on dead end thinking. Even Newton couldn't get anything real out of alchemy.

You do have one thing right.

it has -never- been the science.


Indeed it was never science. It was always fuzzy thinking, even when Newton did it.
